vikranttiwari988-ops/myrepoterraform ? reverse-engineered prompt

Build me a simple Terraform project that can set up an EC2 based GitHub Actions runner using OIDC. I want it to be easy to configure, so I can plug in my AWS account details, repo or org info, and have the infrastructure created without a lot of manual setup. If there are a couple of separate folders already, keep the structure clear and make sure the pieces work together cleanly.

Please make the Terraform files sensible and practical, include the basic AWS resources needed, and add whatever setup is needed for the runner to connect back to GitHub securely. If anything is unclear from the existing files, take a reasonable guess and keep it lightweight. Also add a short README style explanation of how to use it, and if you need current AWS or GitHub docs to avoid mistakes, look them up online.
